Drug Concentration When a drug is injected into the bloodstream of a patient through the right arm, the drug concentration in the bloodstream of the left arm t hours after the injection is approximated by C(t) = at t² + b' for some values a and b. Lab tests show that those values for Artecoadipine are a = 0.28 and b = 5.96, for 0 < t < 24. The model suggests that after injection, the drug concentration of Artecoadipine in the left arm is increasing until some time T hours, and decreasing afterward. Find T. Round to 2 decimal places. hours
